DB News – Real-Time Crypto & Financial News Platform
I built a high-speed news delivery platform for crypto traders, designed to stream critical market updates with millisecond latency. The system aggregates data from diverse sources—blogs, SEC filings, court documents, and Twitter—and delivers curated alerts to users via a web interface, Telegram (premium), and Twitter (free), ensuring traders never miss time-sensitive information.
Key achievements:
Engineered a real-time WebSocket + Pub/Sub architecture to broadcast updates to thousands of concurrent users with <300 ms delivery time.
Optimized PostgreSQL with advanced indexing and partitioning, achieving 3 ms read/write latency and scaling for 1000x future growth.
Implemented secure Redis-based session management, handling 3,000+ daily writes and 15,000+ reads for seamless authentication and authorization.
Integrated Stripe/Coinbase Commerce for subscriptions and built an admin dashboard for user analytics, payment tracking, and content moderation.
This project combined high-performance backend engineering, database tuning, and scalable real-time infrastructure to create a professional-grade, subscription-based news service.
